Wiring for Off-Grid Applications Using Additional Circuit
Breakers in the ACCB Only
The following diagram shows the complete wiring diagram for wiring the
ACCB and Sine Wave Plus Inverter inputs and outputs in an off-grid
application using additional circuit breakers in the ACCB for the outputs
and a 120 Vac generator for input. This diagram also includes the use of a
generator disconnect breaker in the ACCB. Wiring instructions are
provided for making ground connections first (page 1–27), neutral
connections second (page 1–28), and hot connections last (page 1–29).
